TOC Determination in Solid Samples using the Suspension Method

The TOC content in solids plays an important role in the classification of soils, sludges and sediments. According to the German Ordinance on Environmentally Compatible Storage of Waste from Human Settlements, TOC in solid materials is one of the key parameters for the characterization of wastes as part of the acceptance control of landfills. This important control measure requires a fast and simple TOC determination method and, at the same time, a robust and statistically reliable method that is based on the inhomogeneous composition of soils. This application presents an analysis using the TOC-L total organic carbon analyzer.
